Commercial milling systems mill the paddy in stages, and hence are called multistage or multipass rice mills. The objective ofcommercial rice milling is to reduce mechanical stresses and heat buildup in the grain, therebyminimazing grain breakage and producing uniformly polished grain. Compared to villagelevel systems, the commercial milling system is a more sophisticated system configured to maximize theprocess of producing well-milled, whole grains.
The rice milling facility comes in various configurations, and the milling components vary in design and performance. "Configuration" refers to how the components are sequenced. The flow diagram below shows a modern commercial mill catering to the higher end market. It has three basic stages, the husking stage, the whitening-polishing stage, and the grading, blending, and packaging stage.
In modern rice mills, many adjustments (e.g. rubber roll clearance, separator bed inclination, feed rates) are automated for maximum efficiency and ease of operation. The whitenerpolishers are provided with gauges that sense the current load on the motor drives which gives an indication of the operating pressure on the grain. This provides a more objective means of setting milling pressures on the grain.
Object of commercial milling:
A commercial rice miller will have following objectives:
produce edible rice that appeals to the customer- i.e. rice that is sufficiently milled and free of husks, stones, and other non-grain materials
maximize the total milled rice recovery out of paddy minimize grain breakage
The modern rice milling process:
Modern rice milling processes consist of:
In this stage we remove the dust from the paddy,
If the paddy has dust when it is soaking it will pollute the water and influence the nutrition of rice.
The aim of soaking is make paddy absorb enough water, creat conditions for starch pasting.
During the course of starch pasting paddy must absorb above 30% water,
Or it will not be able to fully steam the paddy in next step and thus to influence the quality of rice.
After soaking the inside of endosperm has got many water, now its time to steam the paddy to realize starch pasting.
Steaming can change the physical structure of rice and keep the nutrition, to increase the production ratio and make rice easy to store.
4) drying and cooling.
The aim of drying is to make moisutre reduced from around 35% to around 14%.
To reduce moisture can greatly increase the production ratio and make rice easy to store and transport.
After soaking and steaming it will be very easy to husk the paddy and save energy.
The pearling of pre-boiled rice cost much more time than normal paddy.
The reason is that after soaking the rice is easy to become smectic. In order to avoid this problem we use blowing rice miller, and increase the rotating speed of rice miller, the rice bran transmission adopt neaumatic type to reduce the friction.
7) polishing and grading.
Grading machine is used to separate different quality rice and separate broken rice from the good ones.
Good rice come through the polishing machine, it will make the milling rice become more beautiful color and more smooth, thus to increase the quality of rice.
8) Color sorting.
The rice we get from above step still has some bad rice, broken rice or some other grains or stone.
So here we use color sorting machine to select the bad rice and other grains.
Color sorting machine is an important machine to ensure we can get high quality rice.
The finish rice now is ready dear all! Let's use our automatic weighing and packing machine to make them into 5kg 10kg or 50kg bags. This machine is electric type, you can set it like a small computer, then it will start working according to your request.From this machine you will get bag type rice and you can supply your rice to all your customer!
